ScanQR is a QR code scanner online built for speed, clarity, and privacy. You can scan QR codes from images, screenshots, webcam, and WiFi QR — without installing an app.
Scanning happens on your device in the browser. That means you can preview what a QR code contains (text, link, or WiFi details) before you take action.
Why ScanQR exists
QR codes show up everywhere — restaurant menus, event tickets, WiFi cards, parcel labels, payment stickers. But most "free online QR scanner" sites work the same way: they upload your image to their server, decode it there, and keep who knows what. For a photo of a concert poster that may not matter. For a screenshot containing your home WiFi password, a payment link, or a private document, it absolutely does.
ScanQR was built on a simple rule: the scan should never leave your device. Modern browsers are powerful enough to decode QR codes locally, so there is no technical reason to upload anything. ScanQR runs proven open-source decoding libraries — ZXing and jsQR — directly in your browser tab. No uploads, no server-side processing, no image storage, and nothing for anyone to leak. You can read how this works step by step in the How ScanQR decodes QR codes locally section.
The second motivation was safety. A QR code is just an envelope — you can't see what's inside until you open it, and scam "quishing" stickers exploit exactly that. ScanQR always shows you the decoded content first, so you can inspect a link's domain before visiting it instead of being redirected blindly.
What makes ScanQR different
- Privacy-first: decoding runs locally (no uploads).
- Fast: optimized for real-world QR photos and screenshots.
- Safer scanning: decode first, verify links before opening.

Who builds ScanQR
ScanQR is built and maintained by Naimul Hasan, a software developer focused on privacy-respecting web tools, under Teknikore. The decoding engines ScanQR relies on are open source and publicly auditable — ZXing and jsQR— so you don't have to take the privacy claims on faith.
Safety note: ScanQR shows decoded QR content, but we don’t control third-party websites. Always verify domains before opening links or entering personal information.
